AMD: Southern Islands (7*** series) Speculation/ Rumour Thread
- Thread starter UniversalTruth
- Start date
Performance @ very high resolutions just doesn't seem scale beyond the relative increase in mem frequency - so the Black Edition's ~ 8,1 percent increase in GPU clock appear thwarted by the very mild ~ 3,6 percent increase in mem clock.
Would be interesting to see an OC review explicitly testing the impact of memory clocks/bandwidth @ eyefinity resolutions.

Anyone eelse who has a feeling that 7970 was paper launched?
Already sold out?!

Depends on where you look, OCUK for example has 6 different brands with "10+" in stock (10+ is the highest number they use)

There's just no way to tell. Stock could be decent to good but demand only has to be a little more than stock for the product to sell out. Then again it could be that available stock was low.
So depending on whether you're pessimistic or optimistic I guess is what you're going to think the case is. Unlike some previous launches from AMD/Nvidia we're not hearing many reports on whether initial stock levels were above or below average.
Who knows it could play out like 5870 where it was constantly going in and out of stock for months. Although at that price point, I can't imagine the high initial demand is going to last for months on end.
The absurdly high overclock headroom available on most chips also seems to suggest that yields are quite good which explains why 7950 isn't going to launch until sales for 7970 start to die down. Why sell the exact same chip for less when you can get full price during launch with no need to artificially castrate a chip just so you have stock of a lower tier card to generate more demand and get more sales.
We'll have a better idea of how things are playing out in another week or two when initial launch demand starts to die down. But I do have to wonder if AMD caught themselves in another Cypress situation where they didn't book enough wafers. This time not due to underestimating demand for the chip but instead thinking another foundry would be ready to start producing chips.

With a good powertune implementation, overclocking headroom is pretty much unlimited. The driver can set the clock to what ever it wants. HW will throttle the chip so there's no actual guarantee that your chip ran at that clock.

They had "nearly 200" cards for the launch and still at least 60+ cards in stock. For a large e-tailer that ships also outside of UK that doesn't seem like a stellar rate of sales imo. How about 399€ AMD?
Komplett(.dk/.no/.se) had 200+ cards (took some time for the "100+" sapphire to drop below 100, and the rest summed up to some less than 100) which they sold out on launch day, and then got another 40 or so gigabyte today, which is also sold out now.
That's not really paper imho. But they are pretty expensive considered the $500 (gtx580) vs $550 MSRP...
What I can see from the pictures of overclockers.co.uk for instance is that availability seems prety much equal to the 570/580 launch.
I would just say yield != bin splits.
There could also be some strange bin split distribution caused by the variability of the still quite new process. GPUs often don't have the luxury of the sometimes enormous amount of models based on the same die which means you can market almost every combination of harvested die, speed bin, and power bin (CPUs are examples). In case of GPUs you often have only two (desktop) models. It may require a bit more of thinking to find a good combination of the amount of deactivated units with a certain speed bin while staying at a certain TDP.
You can get one from many different places right now. I'm sure some places have less stock than others. Including obscure etailers such as newegg and amazon.

I'm not sure but if you look at the HIS version it does come with some sort of extended jack from Hardware Haven's review. If Anandtech information is correct the HIS version is the biggest in the group.
According to Overclocker's review it's called the weight lifter. I'm still trying to understand how that installs in the PC case.
Edit: It appears that the weight lifter is design to prevent sag and was used on other video card(s).
That's why I asked if these cards are using the same PCB layout and components. We really need a review showing PCB layout between different AIB's.
